Description

Medios de trabajo médicos exentos de PVC y plastificantes.PVC-free medical work media and plasticizers

La invención se refiere a medios de trabajo médicos, que pueden fabricarse en un procedimiento de extrusión, como tubos flexibles, tubos, catéteres y similares, formados por al menos una capa interior y una capa exterior que la envuelve de materiales polímeros.The invention relates to working means doctors, which can be manufactured in an extrusion procedure, as flexible tubes, tubes, catheters and the like, formed by minus an inner layer and an outer layer that wraps it polymeric materials.

En el estado de la técnica conocido, para medios de trabajo médicos de este tipo se usan sobre todo materiales polímeros basados en PVC, puesto que estos suponen una buena relación entre precio y prestaciones, gracias a los bajos costes de material y la técnica de confección basada en el pegado para elementos de conexión como, por ejemplo, cámaras de goteo, conectores, almohadillas de depresión y otros.In the state of the known art, for media Medical work of this type is used mostly materials PVC based polymers, since these are a good relationship between price and benefits, thanks to the low costs of material and manufacturing technique based on gluing for connection elements such as drip chambers, connectors, depression pads and others.

También se usan medios de trabajo médicos hechos de materiales de poliuretano. Aunque con estos sea posible usar las técnicas de confección existentes, los medios de trabajo médicos de este tipo conllevan la desventaja de una relación negativa entre precio y prestaciones debido al precio de material muy elevado, en particular en aplicaciones en el área de la diálisis y de las transfusiones. Otra posibilidad del estado de la técnica conocido es el uso de medios de trabajo médicos hechos de poliolefinas. Aunque estos tienen un precio de material aceptable, no pueden ser procesados con la técnica de confección convencional como, por ejemplo, el pegado, para obtener instrumentos para diálisis corrientes en el mercado para la hemodiálisis. Los materiales y sistemas que resultan del estado de la técnica conocido presentan, por un lado, una relación desfavorable entre precio y prestaciones y conllevan, por otro lado, asociaciones negativas por la actual discusión del PVC con los temas centrales de la migración de plastificantes, la eliminación de los desechos, como por ejemplo la formación de ácido clorhídrico en la combustión, o la formación de dioxinas y furanos.Medical means of work done are also used of polyurethane materials. Although with these it is possible to use the existing clothing techniques, medical means of work of this type entails the disadvantage of a negative relationship between price and performance due to the very high price of material, in particularly in applications in the area of dialysis and transfusions Another possibility of the known state of the art is the use of medical means of work made of polyolefins. Though these have an acceptable material price, they cannot be processed with the conventional clothing technique as, by example, gluing, to obtain instruments for dialysis current in the market for hemodialysis. The materials and systems that result from the known state of the art present, on the one hand, an unfavorable relationship between price and benefits and entail, on the other hand, negative associations for the current PVC discussion with the central issues of migration of plasticizers, waste disposal, such as formation of hydrochloric acid in combustion, or the formation of Dioxins and furans.

En el documento US5.562.127A están descritos tubos flexibles para el uso médico. Estos están formados por un material compuesto de capas de materiales polímeros, estando descritos tubos flexibles de dos y tres capas. La elección de materiales se hace de tal forma que se evite el uso de PVC. Los materiales preferibles para la formación de los tubos flexibles médicos del documento US5.562.127A no contienen plastificantes. Para la capa interior se indica, por ejemplo, copolímero de etileno y acetato de vinilo con un contenido de un 28% en peso de acetato de vinilo. También se habla de polimetacrilato como material posible para una de las capas. Asimismo se menciona el uso de un copolímero con una poliolefina. Como materiales para la capa interior se indican, por ejemplo, polietileno y polipropileno. Para la capa exterior se indica, por ejemplo, poliuretano.In document US5.562.127A are described flexible tubes for medical use. These are formed by a composite material of layers of polymeric materials, being described two and three layer flexible tubes. The choice of Materials are made in such a way that the use of PVC is avoided. The preferable materials for the formation of flexible tubes Doctors of US5,562,127A do not contain plasticizers. For the inner layer is indicated, for example, ethylene copolymer and vinyl acetate with a content of 28% by weight of acetate vinyl. There is also talk of polymethacrylate as a possible material for one of the layers. The use of a copolymer is also mentioned. with a polyolefin. As materials for the inner layer is indicate, for example, polyethylene and polypropylene. For the cape exterior is indicated, for example, polyurethane.

Further, It is advantageous to use an ethylene methyl acrylate with at least one 10% methyl acrylate. Thanks to the use of polymeric materials this type can be obtained advantageously so that they are not left damaged liquids to be transported through the lumen of the media of medical work preventing, in addition, interactions such as example, a diffusion in the two directions.

En otra configuración ventajosa de los medios de trabajo sobre todo médicos según la invención se usa una poliolefina para la capa interior. Esto tiene la ventaja de que resulta una relación positiva entre precio y prestaciones para los medios de trabajo médicos a fabricar gracias a los precios del material.In another advantageous configuration of the means of work especially doctors according to the invention a polyolefin is used for the inner layer. This has the advantage that it results in a positive relationship between price and benefits for the media medical work to be manufactured thanks to the material prices.

En otra forma de realización ventajosa puede usarse un elastómero termoplástico para los medios de trabajo médicos, que puede ser, por ejemplo, del grupo de los polipropilenos modificados con elastómeros.In another advantageous embodiment it can use a thermoplastic elastomer for work media doctors, which may be, for example, from the group of polypropylenes modified with elastomers.
